Additional Notes
:
When you exit Setup by clicking OK, the driver saves the settings and restores them the next
time you startup – You do not have to repeat the Setup procedure unless you change the focuser
model, install the driver on a different PC, or change the Serial Port.
If you have already established a specific focuser position where you have achieved correct
focus, say at position 3269, and you shut down the system and power down the focuser this
position will be saved internally. When you next power up the focuser and startup the driver
(FocusMax, Maxim DL), the focuser will advance all the way
IN
(and in fact step several steps
beyond, depending upon where it started out, then step
OUT
to position 3269.
If you are sure that the relative mechanical position of the focuser will not be altered significantly
between power cycles, you can check:
The driver will then skip the zero-in and set the step counter to the last value it held at the time
the system was shutdown. This will reduce your setup time, and in most cases your point of best
focus would not have shifted more than a few counts.
Refer to the figure below (Page 7) for an explanation of the various items on the Setup display.
